To all whom it may Be it known that -1 BENaAMIN soN- acitizen of the at if r State' of'Indianahave invented a new and useful Wave-Gravit Pump, of which the 4:followingisa speci cation. The ob'ect of my invention is to provide F. `JACK'- a-novel pui'n'p Y 'a novel'iloat ped to meet ,as nearly .as practicablet-he perpendicular forcerof the wiaves. Itis further my object to provide almechanis'in adapted for the employment of either one or a series of pumps; and to pro- 'vide novel lift and gravity fpumps adapted to be 'operated 'by the single l devised. It is also m object to provide a series of either lift or orce pumps or Ato ro vide `pumps of each. of these types. t is 20,` further my oblect t provide novel means 'for adjusting t eposition ofthe pumps to. .give greaterflexiiity -to the apparatusj "I attanfthese' a `vention by the 4mechanism illustrated in the accompanying drawings, in which Figure 1 isa top plank of the float and the connecting frame;`

un er surface is subject to the buoyancy of thejwave force, and on settling theforce' of ravitation can be almost al1 utilized-,as the v oat being narrow will reach the maximum 5depth .in the trough of kthe waves. In1 its operation on tlieforc'e ump this is the 'result required. A suitab e banister rail 9 encircles the deck of the `float. The bottom of the oat has a long sloping. curve from the front for 'a'distance of approximately two thirds tliewidth before the lowest point is reached f rom which point the bottom of the float is slightly'concave. This shape of surface is arranged in order to accommodate the float to the perpendicular force of the waves morder that the 4maximum of wave force ma be caught and utili'l'ed. "f he float' .is provi( ed with a suitable man-hole cover 10 to pei-mit of ready accessto the interior mechanism for adjusting their length to 11 suitably attached to beam 'T and havilngu second section 12 working therein. The sec` tional shaft 12 is provided with suitable cogs 13. Shaft 1l is provided with a slotted p01'- tion 11, to permit of the operation of the lockinthe event that repairs are needed.r `At `tached to the pump shafts 1 provide novel h igh and low tide conditions. This adj usta- -bili'ty is etiected by means of a hollow shaft ing mechanism.l Suitable cranks 1.5 are. mounted in shaft 11 as shown' in Fig. 4.

They are provided -with lugs 16 arranged to engage cogs 13 of shatt 1:2, as illustrated in Fig. 6. Cranks 15 are held in locked posi` tion normally by springs 17, illustrated in Fig; 4. The cOgs 13 extend almost the entire length of shaft 12y and permit of a consider-Vl able `extension 0r contraction of the pump shaft to 'su-it varying tide conditions. The lug on the upper crank locks'the inner shaft 12 from rising and thelug on thelower locks it from falling through the outer shaft 11:- the arrangement of the lug may, however, be reversed, `as in- Fig. 6, without departin from the princi le ofmy invention. l

I may provi el either a single pump or a In in preferred arrangement lift pumpsare provided at extreme distances from 4the los.

The. gage indicates units Aof length above the center point of the basic .piston Stroke l .The .pump cylinders are .placed as near the buoy or lfloat as conditions will warrant. In case the waves are reguo 4`la`rly of great height the pumps may be and correspondingly farther from the buoy or float. The 'tops of cylinderspreferably pump cylinders are of a size proportionate to the weight and displacement of the float,

and are connected :by pipe lines l25H0 a suitable ijesevoirfor tank at 'an-y practical dis- 'description-of its construction consists of the reciprocation of the pumps roperated from the pivotally mounted frame by means of the rise and fall of the fioat in consequence of the action of the .waves. The peculiar form of thebottom portion of the iioat ma kes 'it possible to utilize the greatestfamount of i power from the waves.

The pumpfshafts may be adjusted by the operation of cranks 15 controlling the sectional shaft 12 so as to lengthen or'- shorten the pump shafts to suit varying ,tide conditions. As the tide rises it is necessary thatv the shaftbefincreased in length; and the reverse'occurs whenthe tide falls. To lengthen the pump shaft the lower lug crank is operated and as'the float rises the inner shaft section is allowed to drop one or two coo's, Aas maybe required, when the f'crank 's a1 owed to return to locked Vosition.

As the'tide falls the shortening oft e shaft is accomplished by drawing the upper lug from" itslocked position by the operation of the'upper crank 15`as thezioat isrising, and the inner shaft is 'allowed to rise the required distance in the vouter section as the float falls. `The crankY is then.`allowed vto return to locked position. The lift-pumps are o erated by the upwardmovernent of the out with an incoming wave. The force pumps are operated by thev weight of the frame 2 and float 1 and the attached mechanism as `the Hoat descends on a vreceding wave by gravity. VThe movement of the valves in the pumps is limited by the vmeans illustrated in Figs. 1.5 and y7` of the accompanying draw- WhatIclaim is:
